Re: looking for pinion/yoke angles...
"Lifted" 4x4s kind of throw a wrench into things with this....
"In theory" your pinion angle (at ride height) should be exactly opposite of the out-put yoke from the transfer case. The "Sticky" part comes in because of the lift. Most lift blocks are angled to tilt the pinion upward, lessening the "overall" angle of the driveshaft, but this "lessens" the angle of the rear joint more than it does the front. This is not "ideal" in the first place, just because the joints are no-longer "equally opposing", but it brings in other issues. First, it tilts the outer pinion bearing up and away from the gearlube.
Second, on axles with the fill plug in the cover, it lowers the "fill level" by rotating the back of the housing downward, which makes the "pinion up" situation worse....
Most of all, never tilt the pinion upward to the point that the driveshaft is straight in line. The there needs to be some angularity between the pinion and the driveshaft, or the u-joint will not last long.
